SPECIFICATION'rming part of Letters Patent NO. 377,494, dated February 7, 1888.

Application filed May 1G, 1887. Serial No. 238,310. (No model.)

To all whom it may. concern.-

Be it known that I, PHILIPP MENGEs, of the city of New York, county and State of vNew York, have invented a new and Improved Gas-Burner, of which the following is a specication.

This invention relates to a gasburner which is so constructed that when the ilaine is accidentally extinguished the cock controlling the 1o supply of gas will be automatically turned olf,

thus checking the further supply of gas.

The invention consists in the various features of improvement, more fully pointed out in the claims. 4

i 5 The following is a full and clear description of my invention, reference being had to the accompanying drawings, in which- Figure l is a side view of my improved gasburner with the gas turned on, but before the gas is lighted. lFig. 2 is a similar View with the gas lighted and the rods expanded. Fig. 3 is a detail view showing the position of the disk and pawl after the gas has been turned off. Fig. 4 is a detail view of the pawl. Fig. 5 2 5 showsa modification of the disk t'. Fig. shows a modification in the numberl of rods e of the burner.

The letter a represents the nozzle in which the gas-supply pipe is screwed and leading to burner b, controlled by cock c, as usual.

carrying two (more or less) rods, e, of brass or other expansiblc metal. Figs. 1 and 2 show the employment of two rods, e. One rod is vrigidly connected at one end to one arm of bracket d, while its other or free end is connected to a liuk,f, pivoted to thc other arm of the bracket. This link is also connected to one end of the second rod e, While the other end of such rod is connected to the gas-controlling device hereinafter described.

In Fig. 6 Ihave shown three rods, e, connected by two links, f, and thus any number of connecting-rods may be used. The advantage of multiplying the number of rods e and connecting them by pivoted links is that the expansion of one rod will be transmitted to and cause a motion of the next rod, and thus the motion of the free end of the uppermost or working-rod will be greatly multiplied. In this way the motion imparted to the gas-controlling devices is increased and more positive,

d is a bracket surrounding burner b andy which is of importance, as I have found that the expansion or contraction of but a singlel rod is not sufficient to cause a perfect or reliable Working of the parts. Y l The free end ofthe working-rod e is attached to a lever, g, which in turn engages a second lever, h, to which there is pivoted a pawl, j,- held against a disk, 1I, having nose z" on the gas- 6o supply cock, by a weighted arm, j', as shown. Of course, the weighty" may be replaced by a spring. Aslotted plate, m, is pivoted to disk i, which is engaged by a pin,j2, on pawlj, and which serves to-control the motion of the pawl.

The operation of the parts is as follows: The gas being turned off, the parts are in the position shown in Fig. 3-that is to say, (the'rods 'e being contracted) the pawlj is out of engage ment with nose i. If the cock is now revolved 7o to turn on the gas, the disk i will be revolved with it to bring the nose '11 down into the position shown in Fig. l. The gas being ignited, the rods e will expand, and by moving leversy g h will cause the pawlj to move downward 75 and to-engage nose fi', as shown in Fig. 2. If the gas is now turned off in the proper manner, the disk i will be brought back into Vits normal position, (shown in Fig. 1,) and the n pawlj will also be brought, after some time, 8o

. into its normal condition by the contraction of rods e; but if the burner should be extinguished accidentally without turning off the cock the lrods e upon contracting will cause the pawl j to gradually move upward, carrying, by nose i', the disk t' with it, andv thus closing the cock and shutting off the further supply of gas. To disengage the pawl from the disk after the cock has been closed,the nose i is brought somewhat above the horizontal line, Fig. 3; or, in other 9o words, it is inclined to the direction of the movement of the pawl. In this way the pawl will under the effect of the contraction of rods eslide toward the front of nose i', and eventu-v ally become disengaged therefrom. Thus the parts are in positionv for the next opening of the gas-cock.'

Fig. 5 shows the disk z provided with two noses instead of one. This construction has for its object to permit an engagement of the roo pawl with the disk on a but partial heating of rods e.

What I claim is- 1. The combination of a gas-burnerA with bracket d, and With e number of expansible the burner-tip, and with the levers g h, pivotrods, e, located above the burnentip, and with ally con nected to such rod, and with a weighted 1 5 the lever, controlling valve or cock, the rods pawl, j, pivotally connected to lever h, and e being pivotally connected to each other, and having a pin7 jz, and With adisk, i, on the gas 5 being also pivotally connected to the bracket supply cock, and having nose '13', and with the 'and to the lever, and with the Weighted pawl slotted plate m on disk fi, the disk i being enj.pivotally connected to the lever, and with a gaged by the pawlj, and the slotted plate m zo disk, fi, on the gascontrolling cock, said disk being engaged by pinj, substantially as specihaving a. nose, i', adapted to automatically disfied.

Io engage from the pawl j, substantially as speci- PHILIPP MENGES.
